SAFETY RzoR.

i Application filed August 1B,y 1921. Serial No. 493,532.

i To all whom t may concern:

Be it known that I, HENRY J. 'GArsMAN, citizen of the United States, andresident ofk New York city, Borough of Manhattan, in the county vof NewYork and State of New York, have invented certain new and usefulImprovements in Safety Razors, ofv

which the following is a specification.

My invention relates toimprovement in safety' razors and lmoreparticularly to the class of razors having a movably supported blade andmovable guard provided with means to cooperatewith the blade to retainvit in shaving position respecting the guard,

and to releas the blade replacement as well as lstropping.

. The object of for removal and forA cleaning and my invention is toprovide slmple, cheap and effective means to mov-.

ably support a guard in av safety razor to retain and release a blade.as required, whereby the blade edge may be retained in proper shavingposition respecting the guard. Y i i My invention comprises noveldetails of improvement that will be more fully hereinafter set forth,and then pointed out inv the. claims.

Refrence is to be had to the accompanying drawings forming part hereof,wherein- Figure 1 is a plan view`of embodying my invention;

Fig. 2 is a sideview of Fig. 1;

Fig. 3 is an underside view in section on line 3, 3, in Fig. 2;

Fig. 4 is an enlarged section on line 4, 4, in Fig. 1; 1

Fig. 5 is a section on line 5, 5, in Fig. 2.

Similar numerals of reference indicate corresponding arts in the severalviews.

The numeralp 1 indicates the mainframe of my improved safety razor whichmay be of any Vsuitable construction, shown provid# ed with al handle 2which may be attached to. the frame in any'well known manner. :Frame 1comprises a base portion 1a and yspaced uprights 1b through which astrop may be passed from lside to side. A blade holder 3 is shownmovably supportedv upon frame 1 between uprights 1" upon a shaft 4pivoted betweensaid upri hts. The blade holder v43 may be of any welyknown variety adapted to securely retain the blade 5, said blade holderbeing shown in the form Vof spaced plate-like members to receive the asafety razorV the guard teeth and heel of the blade therebetween andwith stops 5, 6, at the ends to retain the Lblade removably in theholder. A guard for the blade edge is indicated at 7 shown provided withguard teeth 8 arranged in any well known manner. Said guard is shownpro.- vided with stops or hooks'9 adjacent to its corners to engage theblade edge to retain the blade in .shaving relation to the guard teeth.Said guard is pivotally supported upon base 1a to rock or tiltrelatively thereto to move the guard teeth and the stops 9 with respecttothe blade edge. 'I have guard 7 provided with laterally or downwardlyextending lugs or pivotally connected by pivots orrivets 11 with lugs orears 12 extending from the ends of base 1. Lugs 12 are shown locatedoutside of lugs 11 and in juxtaposition thereto, whereby the guard isrockably retained from lateral or endwise displacement. The guard member7 is provided with an outward projection or thumb piece'. 13 shownprojecting of therazor and provided with an opening 13n receiving handle2, said opening being of suiicient size to permit the projection 13 tobe moved along kthe handle when the guard isvto be rocked. It will beobserved that the pivots 11 are located between `the guard teeth 8 andhandle 2hence between the projection 13. The projection 13 operatesbelow b se'la so that when said projection is pushdl up it will causethe guard to swing away from the blade edge. The movement of projection13 i will bel limited by the base l, Fig. 4. To

base 1 undertension when the pivots l1v are set in the lugs,having,slight clearance' between the end portions of theguard member andbase l.

' I have illustrated my improvement in connection with means for rockingthe blade while. in frame'l comprising a roller 14 journaled in theframe between shaft 4 and base 1,

mesh with a gear 16 securedv to rollenl. -A

beyond the rear portioncorrespondears 10 said shaft having a gear 15 instrop may`be passed between roller 14 and base la and when held taut theblade may be rocked by reciprocating the frame along the strop with theunder surface of roller 14 in engagement with the strop, in a well knownmanner.

lVhen the parts are in the position shown in Fig. 2 stops or hooks 9will engage the blade edge to retain the latter in shaving relation tothe guard teeth 8. Whenit is desired to release the blade from theguard, the projectin 13 is pushed toward base l, lwhereby the guard willbe rocked to move its stops 9 away from the blade edge to release thelatter, as indicated in full lines in Fig. 4, whereby the blade may beraised from the guard by rotating it for removal and` re-placement, forcleaning, and for stropping, since with the blade raised from the guardthe strop may be passed between roller 14and base l, (Fig. 4). When itis desiredto replace the blade in operating. relation to the guard theblade is lowered to rest against the guard member, (which is thenlowered), the projection 13 is drawn down, (as to the dotted position inFig. 4),

causing the outer end of the guard to rise toward the blade edge toengage the stops or hooks 9, whereupon the guard and blade will bein thefull `line position 'shown in Fig. 2 and the dotted line position shownin Fig. 4. j

My improvements are simple in construction, cheap to manufacture, notliable to get out of order, readily operable, and effective in use toretain `the blade for shaving and to release the bladeV for/otherpurposes before specified.

Changes may `construction set forth, within the scope of the appendedclaims. without departing from the spirit of lny invention.

Having now described my invention, what I claim is 1. A safety razorcomprising a frame, al

- to engage and release the blade.

2. A safety razor comprising a frame having a handle, a blade holdermovably carried by the'frame, a guard'having stops to engagethe blade,and means pivota'lly supporting the guard upon the frame between saidstops and handle. said guard having an integral projection for thefinger extending beyond the pivots of thev guard beyond the handle'onthe side opposite the stops.

8. AA safety razor comprising a frame having a handle, a blade holdermovably carried by the frame, a guard having stops' to be made in thedetails oftending beyond the handle, said projection l having an openingreceiving said handle.

4. A safety razor comprising a `trame having a handle and a baseextending on one side of the handle, means on the frame to movablysupport a blade, and a guard pivotally carried by said base on one sideof the handle and provided with stops to engage the blade, said frameand guard having slidably engaging surfaces concentric with saidpivotal-means to frictionally retain the guard.

5. A safety razor comprising a frame having ahandle and a base extendingon one side of the handle, means on'the frame to movably support ablade, said extending portion of the frame having lugs, and a guardhaving lugs pivotally attaehedto the rst named lugs, said guard havingmeans to retain the blade. g

G. A. safety razor comprising a frame having a handle and a baseextending on one side of the handle, means on the frame to movablysupport a blade, said extending portion of the framel having lugs, and aguard having lugs pivotally attached to the first named lugs, said guardhaving means to retain the blade, said guard being provided withaprojection extending beyond said lugs on the side opposite saidretaining means.

7. A safety razor comprising a frame having a handle and a baseextending on one side of the handle, means on the frame to movablysupport a blade, said extending Y portion of the frame having lugs, anda guard having'lugs pivotally attached to the first named lugs, saidguard having means to retain the blade, said guard being .pro-

vided with a projection extending beyond said lugs on the side oppositesaid retaining means, said projection being provided with an openingreceiving said handle.

8. A safety razor comprising a frame having a handle and a baseextending onl one side of the handle, means on the frame `tomovablysupport a blade, said extending portion of the trame having lugs, and aguard having lugs pivotally attached to the first named lugs, said guardhaving means to retain the blade, said guard being. pro-` vided with aprojection extending beyond said lugs on the side opposite saidretaining means, said projection opposing said base to be stoppedthereby when the projection moves the guard away from the blade.
